"将字符串片段名称转换为片段"

Question

我有 8 个片段，分别命名为 Fragment_info_1、Fragment_info_2 等。 我需要将片段动态添加到 TabLayout。 但是如何指定片段的名称vpAdapter.AddFragments(???Name???, );

无法解析符号“Fragment_info_”

'(' 或 '[' 预期

        tabLayout.setupWithViewPager(viewPager);
        VPAdapter_Record_book vpAdapter = new VPAdapter_Record_book(getActivity().getSupportFragmentManager(), FragmentPagerAdapter.BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);
        Intent myintent2 = getActivity().getIntent();
        for (int i = 0, nom = 1; i <= myintent2.getExtras().getInt("Head_size"); i++, nom++ )
        {
            vpAdapter.AddFragments(new Fragment_info_ + i + "()", "Info" + nom);
        }
    
            viewPager.setAdapter(vpAdapter);

您可以使用Fragment_info_1<\/code>作为片段名称的占位符。

        tabLayout.setupWithViewPager(viewPager);
        VPAdapter_Record_book vpAdapter = new VPAdapter_Record_book(getActivity().getSupportFragmentManager(), FragmentPagerAdapter.BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);
        Intent myintent2 = getActivity().getIntent();
        for (int i = 0, nom = 1; i <= myintent2.getExtras().getInt("Head_size"); i++, nom++ )
        {
            vpAdapter.AddFragments(new Fragment_info_(i), "Info" + nom); // or whatever you want to call it!  (I just used the number) 

            viewPager.setAdapter(vpAdapter);

            tabLayout.setupWithViewPager(viewPager);

            viewPager.setCurrentItem(myintent2.getExtras().getInt("Head") - 1); // or whatever you want to call it!  (I just used the number) 

            tabLayout.setupWithViewPager(viewPager);

            viewPager.setCurrentItem(myintent2.getExtras().getInt("Head") - 1); // or whatever you want to call it!  (I just used the number)
